1,10-Phenanthroline–dithiooxamide (2/1)
Abstract
The asymmetric unit of the title compound, C12H8N2·0.5C2H4N2S2, contains one 1,10-phenanthroline molecule and a half-molecule of dithiooxamide, which lies across a crystallographic inversion center. The 1,10-phenanthroline unit is not strictly planar, with dihedral angles between the central benzene ring and the pyridine rings of 1.42 (10) and 1.40 (10)°. In the crystal structure, two 1,10-phenanthroline molecules are linked together by one dithiooxamide via intermolecular N—H...N hydrogen bonds.
